Branching GUI doesn't feel intuitive

I find the branching tools unintuitive and slightly confusing.

Let me give the disclaimer that I understand the practices of branching quite well. I work as a software developer, and I have fairly extensive experience with Git, and to a lesser degree, Subversion and CVS. I've performed an svn to git migration for a major website (a household brand name most people know), and I'm often able to help my colleagues in answering their git questions and provide git workflow solutions to problems when they come up.

That being said, I find branches in OnShape slightly obtuse.

First I have only Start and Main. I discover I must create v1 before I can create v2. At first this is confusing to me, but after more thought, I conclude that Main is analogous to unstaged changes, v1 is analogous to my first commit, and v2 is analogous to a branch created off that commit. After working through it, I can see the logic behind it, but not at first.

I feel like some slight changes could make the representation more intuitive. For example, I don't think I would include unstaged changes as a node in the tree. And since Start is also unstaged changes, I wouldn't include that either. When v1 is created, I would make that the first node. I think it would make more sense to not show any nodes on the graph at first. This would communicate to users that they haven't saved their changes to any branch, and so there is nothing yet for them to branch off of. I think this would also be more clear to people when they then see v1 – v2, and not Main in between v1 and v2, with Start below. Both Start and Main being some other kind of special node which doesn't have all the same privileges that versions have?

Also, why can I change to the start node? There is nothing in the scene at this point. In a code project, I can't change to a point before changes have been committed.

I hope this helps. Actually, writing it has really helped me understand how to use branches in OnShape :).

    An appropriate git analogy would be

    Onshape document history ->  git commits
    Onshape branches  ->  git branches
    Onshape saved versions -> git labels
    Main -> HEAD of your master branch

    And onshape only allows you to create new branches off saved versions.   In most case 'Start' is empty unless the document is created with import geometry in which case it will have something meaningful to branch from.

    Because your work is saved remotely and not on a local disk there's no current working directory and git index on your local machine. Instead you could consider the open circles at the end of a branch to be like that space - an area where your current ongoing work is being made before a change in history is created and committed (to create a new filled circle behind you).

    There may be multiples of these open circles - one at the end of each branch - so that you can 'check out' any of those to do you your work, so that you have a space for your work. Indeed we call them workspaces :-)
